CHARLES G. RICHARDSON, OF SPRINGFIELD, VERMONT.

CLOTH-REST FOR STIEARS.

Application filed May 14, 1915.

To all whom it may concern:

Be it known that 1, CHARLES G. RICH- ARDSON, citizen of the United States, and resident of Springfield, county of \Vindsor, State of Vermont, have invented certain new and useful Improvements in Cloth-Rests for Shears, of which the following is a specificatlon.

This invention relates to machines for shearing cloth and is more particularly concerned with the improvement of the cloth rest construction by which the cloth is supported in proper relationship to the revolving shear and to the ledger blade for the operation of shearing the nap.

The invention is intended particularly to adapt the ordinary wide shear for use in shearing simultaneously two narrow widths of cloth running side by side through the machine with the same degree of eficiency and precision that would be possible if only one width of cloth were running through the machine. It will be understood to those skilled in the art, that the pieces of cloth to be sheared are run into the machine, and the twoends thereof are stitched together to form a sort of endless belt. Of course, where the overlapped ends are stitched together there is an extra thickness of material which necessitates the shifting of the cloth rest out of operative relationship to the shear in order to avoid cutting the cloth at this point. Now when the two narrow pieces of cloth are run through the machine together side by side in this fashion, the stitched ends of the two pieces seldom, if ever, are in alinement, consequently the cloth rest, as heretofore constructed, would need to be shifted to inoperative position whenever either line of stitching reaches the cloth rest. Such shifting of the cloth rest, however, to avoid the stitched ends of one piece, involves the omission of the shearing op eration on a portion of the other piece of cloth that should be sheared, consequently the attempt to use shears, as heretofore constructed, in this manner has led to imperfect or uneven shearing of the nap.

Th present invention embraces substantially a cloth-supporting rest divided transversely at its middle portion into two independently movable sections, each having means for controlling its movement independently of the other.

This and other features of the invention will be explained in this specification, and

' Specification of Letters Patent. Patented Apr, 16, 1918,,

Serial No. 28,097.

will be defined in the claims forming part hereof.

In the accompanying drawings I have illustrated a simple and eilicient form of embodying the principle of this invention.

Figure l is a plan view showing the cloth rest and cloth rest-supporting beam constructed according to my invention;

Fig. 2 is an elevation of the same parts viewed from the back end of the machine;

Fig. 3 is a side elevation of the same parts showing their relation to the ledger blade and the shear;

Fig. 4 is a similar elevation in central section; and

Fig. 5 is an assembled view showing the pertinent portions of a double shear and he actuating mechanism for controlling the cloth rest sections. I

In the practice of my invention, I employ the usual cross-beam or bridge a whose end lugs are securely bolted to the side frames of the machine and whose function it is, in part, to support the cloth rest. This rigid supporting-beam a is provided with a longitudinal recess at its upper end on the side toward the cloth shear c, in order to receive the cloth rest which presents the cloth to the shear and to the ledger blade. The cloth rest Z) is made up of two longitudinal sections divided from each other about midway of the entire length of the cloth rest, the sections being of irregular contour in crosssection, substantially as shown in Fig. 4:.

Each section b is secured to and mounted on a rock shaft 6 which is journaled in a pair of bearing-brackets a 'mounted on the middle and end portions of the supportingbeam a. On the ends of the shaft sections 6' are secured actuating levers 6 by the forward movement of which the rock shaft is turned so as to throw the working edge of the cloth rest sections back away from the revolving shear 0 and the ledger blade d, leaving a gap or space through which the double or stitched end portions of the cloth may pass without being severed. The lower ends of these arms or levers b are engaged by contractile springs Z2 which tend to hold the cloth rest sections in operative position and to return them to operative position when they are released after their shifting movements. The connecting links 6 b on the left and right hand sides of the machine, respectively actuate the left hand and right hand sections of the cloth rest by means of tions in convenient position to be grasped by either hand of the attendant, on either side of the machine.

Each section of the clothrest is provided with an adjustable stop screw (2 whose lower end is in position toabut against the top of one of the fixed brackets so as tolimit the movement of the cloth rest toward the shear. By the adjustment ofthis screw 6, the-space. between the cloth rest, theledger blade and the shear may be varied accordinglto the thickness of the cloth, or the length of the nap to be sheared. The adjusting screw 6 has a notched head which is engaged by a spring keeper 0 to hold it against jarring out of ,pi'oper'position of adjustment.

:From the-foregoing, it will be obvious that two breadths of cloth may be run side by side simultaneously through the machine,

and that the operator can shift or throw back the clothrest section, supporting one piece of cloth, when the stitched ends reach the cloth rest-without disturbing the action oftheshear on the-companion piece of cloth, :thereby making it possible to eliiciently and evenly shear the nap-of each piece of cloth throughout its length without any skipping.

What I claim is: LA clothrest fora cloth-shearing -ma- -.chine divided at-its middle portion into independently movable sections and means for .shiftmg each section separately out of operative relationship to the shear, substantially as described.

2. lnazcloth-shearing machinethe combination of, a transverse supporting member,

a cloth-rest divided transversely into sections and movably supported on said supporting member .and shifting means under the; control OftllGaOPB'FittOl formoving each section of-the cloth rest out of operative relationship to the shear, substantially as described.

:3. The combination with the revolving shear and its let ger blade of, a cloth rest divided into independentlymovable section .rotatably supported on a transverse supporting beam and hand operated mechaposition independently of the other sections,

4. In a cloth shearing machine .the combination of .thetransverse supporting member, two independentlyrotatable rock shaft sections supported thereima cloth rest section secured to each rock shaft for support and movement thereby, a .pair of hand levers which areiconnected respectively with the sections 01" the cloth rest to shift said sect-ions away from operative position and means for automatically, returning each cloth rest section to'operative position, substantially as described.

The combination with a revolving shear and its ledger blade of two separatetransversely alined cloth rest sections-each eX- tending to the middle portion of the shear and mounted to be moved independently into and out of operative relationship to theshear and adjustable means-for limiting themovement of each cloth rest section toward-the shear, substantially as described.
